Yerry - just checked that link. Wow - 1/1.5" is pretty close to APS-C size (at 1.5 crop)! Digic 5 and 14 bit RAW - I think I will look at this one. Like one of the posters before me, I do wish the lens was a bit wider, say 24mm. Is constant apeture of F2.5 required on a camera that doesn't use telecoverters, etc. So variable apeture starting at F2.0 would have been a bonus.

It can't possibly be 1.5". The lens would be bigger and 3x as heavy as the current camera. 1/1.5" (hmmm...a lot like 2/3" isn't it is more like it. A teeeeny bit bigger than the current 1/1.7", but probably not enough to really make room for 14 mp without giving up some ISO / DR performance. Canon seems to be content with the low light & DR performance of all its subframe cameras, and just tries to maintain that level while adding pixels. This is not what I want in either a compact or a crop-frame DSLR............

When some company says we have made x" sensor, they are actually saying that the sensor diagonal is roughly two thirds of that number x in inches. (It's an old '50s tv standard. The number x is the size of the tv tube, not the sensor itself).

Accordingly, Nikon 1 system has a 1" sensor, which is NOT a 25.4mm diagonal, but two thirds of that number, or roughly 17mm which is roughly true (16mm is closer).

So, using the above math, a 1.5 inch sensor has a diagonal of 25.4mm, or a sensor a bit larger than 4/3" (22.5mm)

Hope this helps,

I think we need to wait for something official. If it is 1/1,5, that would make it the same size as the Fuji x10 but still smaller than the Nikon V1. If it is 1.5", that that would make it quite a large sensor and something to celebrate, even without interchangeable lenses.

It drives me crazy the different ways sensor sizes are described. for me I wish they would just say "x"mm by "y"mm.

I'm planning on getting a Fuji X10 shortly. I doubt the G1X will make a difference in my decision as I like the Fuji for build quality / size / good enough photo quality. Also is a few hundred less it looks like.

Yes, did you actually look at that? What they're calling 1/1.5 in that table (Raster Sizes for Various Focal Length Multipliers) is the focal length multiplier, i.e. a 1.5x crop factor which is Nikon's APS-C format.

Note that 1/1.5 ≠ 1/1.5". 1/1.5" = 2/3" which is much smaller than APS-C, and also smaller than the CX sensor in the Nikon 1 (which is approximately a 1" sensor).

Canon Rumors guy got this wrong - it's been floated that this would be bigger than m43 for a while...this camera is designed to attack the fuji's and the sensor size is correct...not the correct CR guy one but the one posted...
